APPARATUS FOR THE PRODUCTION OF DESIGNS IN BAYER, MILLBOABD, VEGETABLELEATHER SUBSTITUTE, AND LINOLEUM SUBSTITUTE.

Application filed December 9, 1922. Serial No. 608,007. I

. To all whom itmay concern Be it known that I, F REDERIC]; KATE, a

Production of Designs in Paper, Millboard,

reland, residing at Ashton-upon-Mersey, in-

the county of Chester, England, have m vented a new and useful Apparatusfor the Vegetable Leather Substitute, and Linoleum Substitute (for whichapplication has been filed'in Great Britain, No. 25,100, September 22,1921), of which the following is a specification.

This invention refers t and consists of new or improved apparatus forcarryingf out a process of producing inlaid pattern e ects in paper,millboard, vegetable leather substitute and linoleum substitute, thesaid process consisting in super-posing layers of coloured pulp or pulpmaterial upon a foundation of pulp (which may be white or coloured) theseveral layers being amalgamated while moist, by pressure and drying,

into a single article. In my copending application, Serial No. 606,006,filed December 9, 1922, I have fully described and.

claimed the process of forming these inlaid pattern efiects.

According to the invention the improved apparatus consists of a machineof the millboard type in which the pulp is run into vats, in each ofwhich is fixed a revolving wire gauze covered cylinder, which collectsthe pulp on its outer surface and carries it upwards to be taken off byan endless travelling blanket or felt pressed against the wire gauzesurface of the cylinder by a couch roll.

The wire-gauze surface of the first cylinder is made in such a mannerthat while such cylinder, and if necessary, a number of succeedingcylinders, may have a plain wire surface to deliver to the blanket orfelt a continuous sheet of pulp, the succeeding wire cylinders fixed inthe direction of movement f the moving felt will have a non-continuousarea of wire-gauze to pick up the pulp. That is to say a desi inwire-gauze, will run over the superficia surface of the cylinder whichwill pick up the pleted design will be taken off in like manner to theusual paper board.

Upon the accompanying drawings:

Flg. 1 illustrates a diagrammatic sectional elevation of a mill-boardmaking machine constructed according to the invention.

Figs. 2, 3 and 4 illustrate plan views of the last three rollers shownin Fig. 1.

Fig. 5 illustrates a cross-section of a detail hereinafter described.

a, a a", a, are the vats for holding the of which revolves in the pulpand collects the pulp on its outer surface, and carries it upwards to betaken ofl'byan endless travelling blanket or felt a, pressed against thewire gauze surface of the cylinder by a small couch roll 01.

Assuming the pattern to be produced consists of coloured bands of threedifferent colours the first vat a will contain the pulp for thefoundation layer, and maybe white or coloured, whilst the other vatswill each contain pulp of one of the predetermined colours.

The first cylinder a will be furnished with the ordinary continuouswire-gauze surface, and on revolving, willconvey to the felt 0 acontinuous layer or sheet of pulp equal in width to the length of thecylinder, and as such layer or sheet is taken off by the felt, it willbe carried forward by the felt past the other cylinders to the deliveryend of the machine. Each succeeding cylinder 6 b, b will be slightlyless in diameter than cylinder b and will be provided with a wire-gauzesurface corresponding to the intended design, or a part of such design.In the example shown, each cylinder b b 7) "is providedwith bands ofwire-gauze which stand away from the cylinder proper, the position ofthe bands on one cylinder registering with the intermediate spaces ornon-gauze covered parts of the other cylinders, see Figs. 2, 3 and 4:.

'With the cylinders thus formed they each pick up bands of coloured pulpfrom their respective vats which are transferred t the foundation layeror sheet of pulp on the felt a in such position as to cause the finalproduct to emerge from the machine in the results in the production of asingle article having an inlaid coloured pattern.

The excess moisture is drawn from the pulp as it passes over thegauze-covered parts of the cylinders in the usual way.

The number of vats and cylinders With different coloured pulp suppliedfrom different stufi' chests will depend upon the thickness of thematerial required and the number of different colours necessary to makeup the design. In this way there may be two or more vats and cylindersfor producing the foundation layer, and two, three or more for thecoloured layers.

In the case of the cylinders carrying the design, or a portion of thedesign, any suitable mechanical device may be employed for the fixing ofthe Wire-gauze which expresses and produces the coloured design for eachseparate colour, one colour only on each separate cylinder. For example,the skeleton parts of the cylinders 6 b 6 before the wire-gauze is fixedon them, may be one, two or more inches of lesser diameter than theplain, Wire-gauze covered cylinders 6 The design may be traced out overthe cylinder by thin bands 6 of suit able metal one, two or more incheswide, see

Fig. 5, fixed vertically on edge over the surface of the skeletoncylinder the wire-gauze being fixed across the upper edges f theupstanding bands of metal, with the necessary strengthening wires, orrods, etc., fixed un der the gauze and supporting it. The rest of theskeleton or frame work, of the cylinders may be covered with thicksheets of water-proof paper, made by the use of rubber latex, or bysheets of tin, wood and other suitable material to prevent the passageof the pulp and water into the interior of the revolving cylinders atsuch parts.

What I claim is Apparatus of the character described comprising a hollowcylinder, spaced bands extending from the surface of the cylinder andcircumferentially thereof, means for securing strips of gauze to thebands Whereby the working surface is raised above the surface of thecylinder to produce the outline of a design, and a non-porous jacketsurrounding that portion of the cylinder free from gauze.

In testimony whereof I have signed my name to this specification.
